An unusual case of preaxial polydactyly of the hand (triplication of the thumbs)

Preaxial polydactyly is the most common duplication pattern in white and Asian populations (1). It is a congen-ital anomaly with a wide range of manifestations .Current classification do not have the capacity to classify all different types of radial polydactyly. We describe here a very rare and unusual case of bilateral preaxial poly-dactyly (triplication) in a woman and report the operations results. We have not found similar case in the litera-ture. Our case is unique and did not fit into the classification systems described for thumb polydactyly.
